sealantsA sealant is a clear or tooth-colored material that the dentist applies to the back teeth. Sealants are placed here to prevent dental decay. By creating a barrier over the back teeth’s chewing surfaces, sealants can help block out the food and germs that cause decay. Sealants are an effective preventive measure, but do need to be replaced about once every 10 years. For more information on sealants or preventive dentistry, call Alamogordo Dental Group soon.
